BED-PLATE FOR PAPER-PULP ENGINES.

SPECIFICATION forming part of Letters Patent. No. 320,721, dated June23, 1885.

Application filed April 9.0, 1885. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK S. TAYLOR, of Eiegelsville, in the countyof WVarren and State of New Jersey, have invented certain new and usefulImprovements in Bed-Plates for Paper-Pulp Engines, of which thefollowing is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is an end elevation of one of my improved bed-plates forpapenpulp engines and the roll, the vat or tub, box, back-fall, androll-shaft being shown in section. Fig. 2 is a plan view of thebed-plate. Fig. 3 is a plan view of the base of the bedplate, part beingbroken away. Fig. 4 is a sectional end elevation of the bed-plate takenthrough the line as as, Fig. 2.

The object of this invention is to provide bed-plates for paper-pulpengines constructed in such a manner as to be less expensive inmanufacture than ordinary bed-plates, and that the cutting or wearingparts when worn out can be replaced at small cost.

The invention consists in the construction and combination of thevarious parts of the bed-plate, as will be hereinafter fully described,and then pointed out in the claims.

A represents the vat or tub, B the baclofall, C the roll, and D therollshaft, of an ordinary paper-pulp engine.

To the bottom of the vat A is secured the box E, upon the upper sideedges of which are formed upwardly-projecting flanges F, to form a seatfor the bed-plate. The bed-plate is secured in placeby keys G, insertedbetween the flanges F and the side edges of the said bed-plate.

The base of the bed-plate is made in two parts, each of which consistsof a vertical clamping-plate H, having upon its inner side a series ofparallel projecting arms, I, the upper edges of which are a little lowerthan the upper edges of the plate H, and which form a support for thebed-plate J. The two parts H I, H I of the base are connected and madeto clamp the bed-plate J by bolts K passing through the said plat-es Hat the sides of the arms I. Between the inner ends of the basearms I isinterposed a bar or block, L, of wood, to make the connection betweenthe two parts of the base firm and rigid.

J is the bed-plate, which is cast in one piece with series of parallelrectangular inclined slots forming series of parallel inclined bars anda series of cross-bars, as shown in Fig. 2. The top of the bed-plate Jis concaved, as shown in Fig. 4, to correspond with the convexed surfaceof the roll 0. Vith this construction the bedplate J is the only partsubject to wear, and the said bed-plate when worn can be readilydetached and replaced by a new one.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl. The cast-metal bed-plate J, made with aseries of inclined slots forming a series of inclined bars and a seriesof crossbars, substantially as herein shown and described.

2. The combination, with the cast-metal bedplate J, of the clampingbarsH, having in Wfll'dlY-PIOJQChllJg arms I to support the said bed-plate,the wooden bar L, interposed between the ends of the arms I, and thetransverse fastening-bolts K, substantially as herein shown anddescribed, whereby the said bedplate will be firmly supported, securelyheld in place, and can be readily detached and replaced, as set forth.

FREDERICK S. TAYLOR.
